Since I have never pre-filled an oil filter, exactly how do you do it? Do you fill both sides of the filter medium or just one? and....how?

Hi Matt,
What I did was pour some oil into the center hole in the filter. The one with the screw on threads. The oil level will drop as the filter elements become saturated with oil. I can't say if enough oil goes through the filter element to fill the "outside of the filter. Just before I am going to install the filter I fill the center of the filter about 2/3 full and spin it on. Access on the C14 is easy so you can hold the filter upright until you flip it horizontal to install. I did not have any significant oil loss from the filter. When I change the oil and pre-filled the filter the oil light went out within seconds.
How it works, I don't know
Why it works, I don't know.
I do know that in this case it "fixed" my problem with excessive long times to get oil pressure.
If you have experienced this problem, give this a try.
